The only known photo of Libby Prison,Civil War confederate prison camp , in Richmond, Virginia, was one of the most notorious Confederate prisons in operation during the Civil War. The building was originally a tobacco warehouse, constructed by local merchant Fulton Libby in 1845; by 1862, it was a filthy, vermin-infested, dank prison, housing as many as twelve hundred Union soldiers in six rooms each no more than forty by one hundred feet. Many prisoners died there; those who survived suffered from poor health for the rest of their lives
